FIELD OF THE INVENTION

This invention relates to a new catalyst or catalyst precursor. Moreparticularly this invention relates to a novel mixed transition metaloxide and its use as a catalyst or catalyst precursor such as ahydrocarbon conversion catalyst or catalyst precursor or specifically ahydroprocessing catalyst or catalyst precursor. The hydroprocessing mayinclude hydrodenitrification, hydrodesulfurization, hydrodemetallation,hydrodesilication, hydrodearomatization, hydroisomerization,hydrotreating, hydrofining, and hydrocracking.

BACKGROUND

Currently there are two main drivers for refiners to invest inhydroprocessing technology. The first being environmental regulationsimposing more stringent specifications on fuels including gasoline,diesel, and even fuel oils. For example, permitted sulfur and nitrogenlevels in fuels are significantly lower than one decade ago. A seconddriving force is the quality of crude oils. More refineries are facingcrude oils containing higher concentrations of sulfur and nitrogencompounds which are difficult to process or remove by conventionalprocesses. Without new technology, refiners resort to increasing theseverity of hydrotreating processes either by increasing the reactortemperatures or decreasing space velocity through the reactor.Increasing reactor temperature has the drawback of shortening catalystlifetime. Decreasing space velocity, through increasing reactor size ordecreasing feed flow rates, has the drawback of overhauling the reactorsor significantly reducing production rates. Therefore, a highly activehydroprocessing catalyst is needed. A highly active hydroprocessingcatalyst helps the refiners meet the stringent fuel sulfur and nitrogenlimitations without significant investment in reactors and equipment andwhile maintaining production rates.

In the early 2000s, unsupported, also called “bulk”, hydrotreatingcatalysts were applied in commercial hydrotreating processes. Thesecatalysts were claimed to have several times more activity thanconventional supported NiMo or CoMo hydrotreating catalysts based on thesame loading volumes. However, to achieve the high activity, theunsupported hydrotreating catalysts often contained significantly moremetal content than the conventional supported hydrotreating catalysts.Increased metal content means the cost of the catalyst is alsoincreased. Thus, there is a need in the industry for an unsupportedcatalyst with better intrinsic activity per mass. An unsupportedcatalyst with higher intrinsic activity per mass will require less metalloading to achieve the same activity as the unsupported catalyst withless intrinsic activity at the same loading volumes. One way ofimproving the intrinsic activity of unsupported catalyst is by mixingmaterials such as Al or Si with NiMoW during the synthesis. Theintrinsic activity of an unsupported catalyst is improved when Al or Sicontaining NiMoW has the similar activity as NiMoW-only materials on theweight basis.

NH₄is an ammonium cation with one positive charge. OH and O are hydroxideanion and oxygen anion with one or two negative charges, respectively.a, b, c, and d are the valence states of M_(I), M_(II), M_(III), andM_(IV); x, y, m, n, o, p, q, and r are the mole ratio of [R1 R2 R3 R4-N]cation, NH₄ cation, M_(I), M_(II), M_(III), M_(IV), O, and OH anion,wherein m/(m+n)≥0 and m/(m+n)≤1, wherein (m+n)/o is from 1/10 to 10/1,wherein o>0, wherein x, p, and r are each greater than 0, wherein y isgreater than or equal to 0, and a, b, c, d, x, y, m, n, o, p, q, and rsatisfy the equation:x*(+1)+y*(+1)+a*m+b*n+c*o+d*p+q*(−2)+r*(−1)=0

The material is further characterized by an X-ray diffraction pattern,which is essentially amorphous with crystalline peaks shown in Table Aif M_(IV) is Al or Table S if M_(IV) is Si:

Patterns presented herein in tabular form or as patterns were obtainedusing standard X-ray powder diffraction techniques. The radiation sourcewas a high-intensity, X-ray tube operated at 45 kV and 35 mA. Thediffraction pattern from the copper K-alpha radiation was obtained byappropriate computer based techniques. Powder samples were pressed flatinto a plate and continuously scanned from 3° and 70° (2θ). Interplanarspacings (d) in Angstrom units were obtained from the position of thediffraction peaks expressed as θ, where θ is the Bragg angle as observedfrom digitized data. As will be understood by those skilled in the artthe determination of the parameter 2θ is subject to both human andmechanical error, which in combination can impose an uncertainty ofabout ±0.4° on each reported value of 2θ. This uncertainty is alsotranslated to the reported values of the d-spacings, which arecalculated from the 2θ values. The intensity of each peak was determinedby the peak height after subtracting background. To prevent errors inpeak deconvolution, the background is taken to be linear in the rangedelimiting the broad diffraction features, 6-2 Å. I_(o) is the intensityof the peak at 2θ of 32.0-41.50 if M_(IV) is Al or the intensity of thepeak at 2θ of 32.0-36.5° if M_(IV) is Si. I/I_(o) is the ratio of theintensity of a peak to I_(o). In terms of 100(I/I_(o)), the abovedesignations are defined as: vw=0-5, w=5-20, m=20-60, s=60-80, andvs=80-100. It is known to those skilled in the art, the noise/signalratio in XRD depends on scan conditions. Sufficient scan time isrequired to minimize noise/signal ratio to measure peak intensities.

Theselection of binder includes but is not limited to, anionic and cationicclays such as hydrotalcites, pyroaurite-sjogrenite-hydrotalcites,montmorillonite and related clays, kaolin, sepiolites, silicas, aluminassuch as (pseudo) boehomite, gibbsite, flash calcined gibbsite,eta-alumina, zirconia, titania, alumina coated titania, silica-alumina,silica coated alumina, alumina coated silicas and mixtures thereof, orother materials generally known as particle binders in order to maintainparticle integrity. These binders may be applied with or withoutpeptization. The binder may be added to the bulk mixed transition metaloxide material, or may be incorporated during synthesis. The amount ofbinder may range from about 1 to about 80 wt % of the finishedcomposition, or from about 1 to about 30 wt % of the finishedcomposition, or from about 5 to about 26 wt % of the finishedcomposition. The binder may be chemically bound to the mixed transitionmetal oxide material, or may be present in a physical mixture with thenovel mixed transition metal oxide material. The mixed transition metaloxide material maybe extruded or pelletized with or without a binder.

At least a portion of the mixed transition metal oxide material, with orwithout a binder, or before or after inclusion of a binder, can besulfided in situ in an application or pre-sulfided to form metalsulfides which in turn are used in an application. The sulfidation maybe conducted under a variety of sulfidation conditions such as throughcontact of the mixed transition metal oxide material with a sulfurcontaining stream or feedstream as well as the use of a gaseous mixtureof H₂S/H₂. The sulfidation of the mixed transition metal oxide materialis performed at elevated temperatures, typically ranging from 50 to 600°C., or from 150 to 500° C., or from 250 to 450° C. The sulfiding stepcan take place at a location remote from other synthesis steps, remotefrom the location of the application where the mixed transition metaloxide material will be used, or remote from both the location ofsynthesis and remote from location of use. The materials resulting fromthe sulfiding step are referred to as metal sulfides which can be usedas catalysts in conversion processes.

As discussed, at least a portion of the mixed transition metal oxidematerial of this invention can be sulfided and the resulting metalsulfides used as catalysts in conversion processes such as hydrocarbonconversion processes. Hydroprocessing is one class of hydrocarbonconversion processes in which the mixed transition metal oxide materialis useful as a catalyst. Examples of specific hydroprocessing processesare well known in the art and include hydrodenitrification,hydrodesulfurization, hydrodemetallation, hydrodesilication,hydrodearomatization, hydroisomerization, hydrotreating, hydrofining,and hydrocracking. In one embodiment, a conversion process comprisescontacting the mixed transition metal oxide material with a sulfidingagent to generate metal sulfides which are contacted with a feed streamat conversion conditions to generate at least one product.

The operating conditions of the hydroprocessing processes listed abovetypically include reaction pressures from about 2.5 MPa to about 17.2MPa, or in the range of about 5.5 to about 17.2 MPa, with reactiontemperatures in the range of about 245° C. to about 440° C., or in therange of about 285° C. to about 425° C. Contact time for the feed andthe active catalyst, referred to as liquid hourly space velocities(LHSV), should be in the range of about 0.1 h⁻¹ to about 10 h⁻¹, orabout 0.25 h⁻¹ to about 8.0 h⁻¹. Specific subsets of these ranges may beemployed depending upon the feedstock being used. For example, whenhydrotreating a typical diesel feedstock, operating conditions mayinclude from about 3.5 MPa to about 8.6 MPa, from about 315° C. to about410° C., from about 0.25 h⁻¹ to about 5 h⁻¹, and from about 84 Nm³ H₂/m³to about 850 Nm³ H₂/m³ feed. Other feedstocks may include gasoline,naphtha, kerosene, gas oils, distillates, and reformate.
